ABSTRACT OF THE DISCLOSURE A method for microphotometering individual volume elements of a microscope specimen, comprising generating a luminous dot or cursor and progressively illuminating a plurality of part elements in the focal plane of the microscope through the specimen. The mutual position between the specimen and the focal plane is then changed and a plurality of part elements in the focal plane are illuminated. Reflected and/or fluorescent light and transmitted light respectively created by the illumination is collected, detected and stored for generating a three-dimensional image of that part of the specimen composed of the volume elements. Illumination of multiples of part elements is implemented by deflecting the cursor and/or by moving the specimen. The change in the relative mutual position between the specimen and the focal plane of the microscope is effected either by displacing the specimen or the objective. Apparatus for carrying out the method include a specimen table, a microscope objective and light source. The table or the objective are arranged for stepwise movement along the main axis of the microscope synchronously with punctilinear light scanning of the specimen. The table is arranged for stepwise movement at right angles to the main axis and/or the light source is arranged for deflection over the focal plane through the specimen.
